COMBINED DUMPlNG-SCRAPER ANDVIDUMPINYG DEVICE.

SPECIFICATION forming part of ,Letters Patent No. 768,428, dated August 23, 1904.

' Application filed November 25, 1903. Serial No. 182,637- (mi model.) i

To all whom, it may concern:

Beit known that I, WILLIAM S. DEIDRICH, a citizen of the United States, residing at Macon, in the county of Bibb and State of Geor' gia, have invented a new and useful Combined Dumping-Scraper and Dumping Device, of which the following is a speclficatlon.

The objects of my invention-are to provide. a dumping device for scrapers of simple, du-

rable, and inexpensive construction, to which the scraper can be easily and readily connected with and disconnected from at the pleasure of the operator.

A further object is to provlde a dumping device which is designed tobe attached tothe ordinary scraper now in use, Which will allow the scraper to be drawn forwardly a certain distance over the ground-surface, and thus cause it to be filled, and when thescraper reaches a vcertain predetermined point the dumping device will operate to raise the rear portion of the scraper upwardly and as the forward movement of the scraper is continued drawn rearwardly to itsv point of starting.

The general purpose of the device is to provide a scraper which can be used for building an embankment which can be made to dump constantly at the same point without the assistance of an operator.

My invention consists in certain details in the construction, arrangement, and combination of the variousparts of the device whereby the objects contemplatedare attained,-as hereinafter more fully set forth, pointed out in my claims, and illustrated in the accompanying drawings, in which Figure 1 shows in perspective the device in posltion for use, showing the means for drawing the scraper forwardly and rearwardly In A and the meansfor dumping the scraper. this view'the scraper is shown in the position in which it stands immediately after it has been dumped and-in dotted lines in itsposition at the point of starting. Fig. 2 is a front elevation of the scraper in a dumped position; and Fig. 3 is a detail view of a portion of one side ofthe scraper, showing the hook to which the draft devices are attached. I

Referring to the accompanying drawings, I haveused the reference-numeral 10 to'indi- "cate ,a post which is designed to be mounted in the ground some distance beyond the place where the dirt is to be dumped.

The reference-numeral 11 indicates a strip which is firmly attached to one side of said post and some slight distance away from it to form a slot 11 between the exterior of the post and the. interior of said strip. Extending throughthe strip is a series of openings 11", designed to admit the pins 11 ,11 and 11 There is a series of openings extending into the post immediately inside and in line with the openings 11, so that as anypne of the pins 11", 11 or 11 is inserted into one of the openings 11 it will pass into one of the openings in the post 10. Mounted on that portion of the pin 11 which is inside of the strip 11 and the outside of the'p'ost 10 is a roller 11 The reference-numeral 12 indicates a stake which is driven into the ground some distance outside of the post for the purposes hereinafter made clear.

The reference-numeral13 indicates a second stake, which isdriven inthe ground a'considerable distance inside of the post 10' and some distance behind the point where ,the dirt which is to be removed lies. Firmly attached wardly and upwardly over thepulley 11 is a cab'lelA, having its extreme forward end extending downwardly from the pulley 11 to the stake 12, to which it is attached. The cable 14 is designed to be held rigidly'in position'and constantly kept taut by the stakes at one end to the stake 13 and extending for- 12 and 13 and the pulley 11, so that from the pulley 11 to its point of attachment the cable 14: is inclined downwardly. The pulley 11 is thus mounted on the pin 11 so that by simply removing the pin 11 the pulley 11 can be raised or lowered to increase or diminish the slope of the cable 1 1 from said pulley to its point of attachment to the post 13. Thus by untying the cable from either of the stakes 12 and 13 and lengthening the cable the pulley can be raised upwardly, and thus the incline of the cable 1 1 will be increased between the pulley 11 and the stake 13. Mounted on the cable 14 is a pulley 15, which is designed to move longitudinally of that portion of the cable which is between stake 13 and the upper portion of posts 10 and 11. This pulley is so arranged that it can be easily detached from the cable 1 1 at the pleasure'of the operator.

I have provided a scraper or scoop 16, with which the grading is to be done. This scoop has the handles 17 attached to its rear upper portion and has a rounded bottom and sides and also has a sharpened forwardly end which is designed to engage the ground and cause the scraper to be filled with dirt as it moves forward over the ground-surface. Attached to each side of the scoop and extending rearwardly from its point of attachment to the scoop is a chain 18. To the chains 18 the device for drawing the scraper or scoop rearwardly is to be attached. Mounted on the hooks 19, to which the chains 18 are attached, is a bail 20, which is substantially semicircular in shape and extends from the pivotal point 19 on one side of the scraper, in front of the scraper, to the pivotal point 19 on the opposite side of the scraper. There is a loop 21, to which the draft device for drawing the scraper forwardly is attached, midway between the ends of the bail. At the rear upper portion of the scraper is a loop 22. Attached at one end to the pulley 15 and at its other end to the loop 22 is a rope 23, so arranged that when the pulley is at its lower limit of movement on the cable 14 the rope will hang loosely, but as the scoop moves forwardly over the ground-surface the rope 23 will cause the pulley 15 to move upwardly on the cable 14:, and when the pulley reaches a point where the distance beween the pulley and its point of attachment to the scraper 16 as the scraper lies on the ground-surface becomes greater than the length of the rope the rear end of the scraper will be drawn upwardly, and if the forward drawing force on the scraper 16 is continued the rear end of the scraper will be elevated and the scraper be allowed to swing from a horizontal to a complete vertical position and off the groundsurface entirely, and thus afford a complete dumping of the scraper. A further description of the scraper is deemed unnecessaey, as

it is of the Ol'tlllltll') construction.

\Vhen the scraper has been dumped, it is drawn rearwardly, and the pulley 15 moves rearwardly on the cable 11 to its point of starting.

It is to be understood throughout the entire description that forwardly means toward post and rearwardly means away from said post.

Preferably in use of my scraper a pulley 2 1is mounted upon that portion of the pin 11 which is between the strip 11 and post 10 is a pulley 241, and mounted on that portion of the pin 11 which is between the strip 11 and the post 10 is a pulley 25. 'lhese pulleys 2 1 and 25, which are thusmoun ted on the pins 11 and 11 so that their position can be changed easilythat is, by removing the pin 11 the pulley 21 can be moved upwardly or downwardly and the pin inserted into one of the openings either above or below in the position shown in Fig. 1 of the drawings. The same can be done with the pulley 25, if desirable. Detachably connected with the loop 21 is a cable 26, which passes over the pulley 24: and under the pulley and is attached at its other end to a windlass, which is designed to be operated by a stationary engine 28, so that if the windlass is d riyen in one direction the cable will be wound up and the scraper will be drawn forwardly and as it is driven in the opposite direction the cable will be allowed to unwind. Preferably, also, I have attached a cable 29 to the rear ends of the pins 18, which is passed around the pulley 30, which is attached to the stake 13 and attached to the second windlass 31, which is connected with the engine 28 and which when rotated in one position will cause the cable 29 to be wound upon it, and thus the scraper will be drawn rearwardl y, and when the windlass 31 rotates in the opposite direction the cable unwinds from said windlass. This windlass 31 is also driven by the engine 28. llowever, it is to be understood in this connection that a horse or other draft-animal can be attached by any device to the loop 21 and cause the scraper to be drawn forwardl y, or the scraper may be drawn forwardly or rearwardly in any other desirable way.

In practical operation and assuming the parts in the manner above described and the scraper is in position adjacent to the stake 13 and the pulley 15, which is at its lower limit of movement, the engine is put into operation to wind the cable 26 upon the windlass 27, and thus draw the scraper forwardly. 'lhe scraper is generally designed to be guided by an operator who grasps the handle 17.

scraper moves forwardly, the pulley 15 moves upwardly and forwardly on the cable 11 until it reaches a position where the rope 23 begins to draw the rear end of the scraper upwardly.

If the rope 23, and the pulley 1'5, and the substance on the interior of the scraper will bedumped.

The second windlass,31, is then set into operation to wind the cable-29upon it and draw said scraper to its point of starting, and as it is drawn rearwardly the pulley 15-will move rearwardly and downwardly on the cable 14,

and thus the scraper will take its normal position, as shown in dotted lines of Fig. 1 of the drawings. It will be seen that if it is desired to build an embankment it will be desirable to have the scraper drawn to the top of the embankment before it'is dumped, and this is accomplished by adjusting the pulleys 11 and 24:. An inclined track may of course beused in place of the inclined cable 14:, as the operation would be the same whether a tract or cable were used.
